In this groundbreaking history of the modern American metropolis, Richard Rothstein explodes the myth that America's cities came to be racially divided through de facto segregation - that is, through individual prejudices, income differences, or the actions of private institutions like banks and real estate agencies. Rather, he incontrovertibly makes clear that it was de jure segregation - the laws and policy decisions passed by local, state, and federal governments - that actually promoted the discriminatory patterns that continue to this day.
